DNS Monitoring Across Networks

Without working DNS your network is dark. ThousandEyessheds light on the performance of your DNS infrastructure,from caching servers to external providers.

Monitor Your DNS Servers, Resolvers and Vendors

ThousandEyes monitors the performance of DNS servers, resolvers and records in your network, those of your vendors and across the DNS hierarchy. See DNS performance side-by-side with routing,
path tracing and application availability data to help you make more informed decisions. ThousandEyes gives you visibility to solve DNS problems such as server performance, caching errors,
record misconfigurations and cache poisoning.

Troubleshoot DNS Server Errors

Easily monitor on-premises, hosted or third-party DNS servers to check availability, resolution time and recordmappings. Detect and diagnose issues with both authoritative DNS servers and local resolvers.

Monitor DNS Vendor Performance

Most organizations rely on external DNS registrars and hosts, but have little understanding of outages.

See the DNS Hierarchy

Trace the entire DNS hierarchy for a record, from top level domain servers to the authoritative server
and understand if DNS infrastructure outside of your control is causing an outage or performance degradation.

Trace Queries Through the Hierarchy

Measure availability of eachserver in the hierarchy, total numberof queries and query time.

Detect Cache Poisoning

Detect DNS cache poisoning in your network or in remote networksby alerting on record mappings.
